Unable to run in simulation mode, only mock mode

[jason-james]

My program is working fine in mock mode, however I'd like to run in simulation mode to make use of the enclave.so file. When I run it, it says it can't find libsgx_urts_sim.so as below.

Could not load SGX secure worker binary:
Error: libsgx_urts_sim.so: cannot open shared object file: No such file or directory

Mock implementation will be used instead. Do not use in production.

This issue is solved by others (presumably not using secureworker) by ensuring their environment variables are set and if that doesn't work then setting a file in r /etc/ld.so.conf.d and running ldconfig, but this doesn't work in my case. Any suggestions? Is simulation mode supposed to work with this package? The file its referring to definitely exists.
